DEPTH-GAGE.

To all whom 'it may concern:

Be it known that I, JACOB S'rnuss, a subject of the Czar of Russia, and a resident et Elizabeth, in the county of Union and State of New Jersey, have invented a new and Improved Depth-Gage, of which the following is a full, clear, and exact description.

The invention is an improvement in depth gages, and ha-s in view such a device in which a shifting of the blade from one point of the stock to another does not require the transfer of the binding member or screw.

The invention further resides in an instrument of this character in which a cylindrical, as well as a flat, depth blade can be used.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of a depth gage constructed in accordance with my invention, showing the blade in use at the end of the stock, and in dotted outline at an intermediate point of the stock; Fig. 2 is a perspective view of the gage with a flat blade arranged at an intermediate point of the stock; Fig. 3 is a side view of the gage partly in longitudinal central section; Fig. 4L is a section on the line 4 4 of Fig. l; Fig. 5 is a section on the line 5-5 of Fig. 2; and Fig. 6 is a detail view, in perspective, of the binding member or screw.

In the construction of my improved depth gage, I provide a gage stock 5 having keepers 6 transversely arranged at different points along its length, ordinarily one of these keepers being provided at the end of the stock and the other at or near the center. The keepers 6 are preferably in the nature of slots, each formed intermediate the width of the blade and of a form as best shown in Figs. 1 and 2, wherein it is seen that the slot is of a character to receive a flat or angular blade 8, and is enlarged at the center to receive a cylindrical blade 9. Either of these blades is adapted to be secured in adjusted position in either of the keepers by a binding member or screw l0, which screw is preferably arranged on the longitudinal center of the stock between the two keepers, Y

and is threaded in a nut 11 freely rotatable in an opening 12 formed in the stock. The screw is held against rotation, while allowed Specification of Letters Patent.

Serial No. 586,206.

to freely travel longitudinally, by splining one of its ends, which is shown at 13 in Figs. 3 and 6 to be flattened.

In clamping either' of the blades in adjusted position in either of the keepers, the screw is adjusted so that its end adjacent to the blade will bear thereagainst. In transferring `the blade to the other keeper it is only necessary to loosen the screw suiiiciently to disengage the blade and place the blade in the other keeper, when a further movement of the adjusting screw in the same direction presses the opposite end thereof against the blade. The screw although long enough to bind either of the blades in either of the keepers is yet sufficiently short to stand in a neutral position so that either of the blades can be entered into either of the keepers without shifting the screw in either direction. The construction of the depth gage not only makes it unnecessary to transfer the binding screw in changing the blade from one keeper to another, but also obviates the projection of the binding screw and nut as usually employed, from one side of the blade.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. In a depth gage, a stock having keepers spaced apart, and a binding member carried by the stock and adjustable to bind at one end the blade in one of the keepers, and at the opposite end the blade in the other of said keepers.

2. In a depth gage, a stock having keepers at different points along its length transversely arranged, a binding screw arranged within the stock, and a nut through which the screw is threaded, located in a recess in the stock and adapted to adjust the screw to bind at its opposite endsthe blade in the respective keepers.

3. The combination of a stock having keeper slots passing therethrough and respectively arranged near one end and at an intermediate point of the stock, a blade adapted to slide in either of the keepers, a screw arranged within and slidably splined to the stock, and'a nut threaded on the screw and arranged in a recess in the stock, adapted to adjust the screw to bind at its opposite ends the blade in the respective keepers.

4. In a depth gage, a stock having an angular keeper slot passing transversely therename to this specification in the presence of through for lat blades, the slot provided tWo subscribing Witnesses.

With an enlaroed rounded portion at an intermediate piint, for cylindrical blades, JACOB STIRISS and a binding member arranged to bind Witnesses: either form of the blades in the keeper slot. W. W Hom,

In testimony whereof I have signed my PHILIP D. RoLLHAUs.
